Claims. (Cl. 74-16) This invention relates to mounting means, particularly means to mount a powering unit for a power tool and/ or equipment. In a more specific aspect, this invention relates to mounting means for such a powering unit having therewith indexing means. In still a more specific aspect, this invention relates to new indexing and mounting means for a power unit having a motor with a power pulley and a pulley belt therefor, such motor and belt assembly operable to power a plurality of stationary power tools and/ or equipment which is spaced around, over and/or under table supporting and positioning means, and such power tools and/ or equipment having drive pulleys to operatively receive the belt which is powered by the motor.

It is old in the prior art to mount motors and other types of powering units on tables, platforms, frame supporting means, and the like. Further, it is known in the prior art to mount a plurality of power tools and/or equipment in spaced relation and drive the tools and/ or equipment from a common powering unit or motor, for example, apparatus is known which mounts a plurality of such tools and/or equipment on a rotating turntable which moves the tools to an indexed position for driving by a motor centrally mounted of the purality of tools and/or equipment. And, of course, it is known in the prior art to drive a plurality of tools and/or equipment from a common shaft of the nature of a drive shaft which is powered by a single motor or other powering unit.

All of these methods and means of the prior art have their disadvantages. The apparatus which mounts power tools and the like rotatably relative to a fixed motor or powering unit is very complicated, expensive to build and maintain, and is not convenient to use. Paritcularly, tools cannot be positioned idealistically relative to shop space and the operation performed by the tool or equipment. The indexing means must be built into the turntable proper in operating combination with the means for rigidly mounting the motor or powering unit. This necesstates costly and inconvenient indexing. A rotating table which mounts and carries relative heavy tools and/ or equipment and which rotates, requires an extraordinarily strong structure, and is subject to getting out of alignment with the motor power take-01f frequently.

The new indexing and mounting means of my inven tion for a powering unit used to drive a plurality of power tools and/or equipment which are mounted in spaced relation overcomes all the disadvantages of the apparatus and devices of the prior art. The new indexng and mounting apparatus of my invention is simple and easy to build, very portable, and convenient and easy to use and maintain. It is properly used with rigidly mounted and spaced power tools and/ or equipment, and because of the rigidity of mounting, these tools can be much better mounted and positioned for use than in the apparatus of the prior art.

The new indexing and mounting means of my invention for a powering means which is used to power a plurality of power tools and/ or equipment has a mounting member which is mountable tiltably and in turning relation to the plurality of power tools and/ or equipment. This mounting member is constructed and adapted to receive and mount the powering means, and when so mounted it tilts and turns with the mounting member. The apparatus has means connected to the mounting member which are operable to tilt it, and thus the powering means. Indexing means with the mounting member are employed and they are operable to lock the mounting member in more than one pcsition'relative to means in which the mounting member is mounted in turning relation. The indexing and mounting means has means therewith which are constructed and operable to operate the indexing means.

It is an object of my invention to provide new indexing and mounting means for a powering unit.

It is another object of my invention to provide new indexing and mounting means for a powering unit operable to power a plurality of power tools and/or equipment which are mounted in spaced relation.

Still another object of my invention is to provide new indexing and mounting means for a power unit having a motor with a power pulley and a pulley belt therefor and operable to power a plurality of stationary power tools and/ or equipment spaced around, over and/ or under a table and having a drive pulley to operatively receive the pulley belt which is driven by the motor.

Still a further object of my invention is to provide simple and easy to build indexing and mounting means for a powering unit such as a motor, which is convenient to use, easy to maintain, and portable.

Other objects and advantages of the new indexing and mounting means for a powering unit of my invention will become apparent to those skilled in the art upon reading this disclosure.

Drawings accompany and are a part of this disclosure. These drawings depict preferred specific embodiments of the new indexing and mounting means for a power unit of my invention, and it is to be understood that the drawings are not to unduly limit the scope of my invention.

Following is a discussion and description of the new indexing and mounting means of my invention for a powering unit. The description and discussion is made with reference to the drawings whereon the same reference numerals are used on the same or similar parts and/ or structure, and reference is made to these numerals. It is to be understood that the following discussion and description is not to unduly limit the scope of my invention, because such discussion and description is of preferred specific embodiments of the new indexing and mounting means for a powering unit of my invention.

The new indexing and mounting means for a powering unitof my invention is particularly desirably used to tiltably and rotatably mount a motor 7. This motor 7 has a power pulley or take-oil 9 which drives a pulley belt ii.

Patented Mar. 28, 1951 A pulley belt 11 is preferred, however, as one skilled in the art will appreciate, other driving and connecting means such as a spocket and chain belt common to the art can be used, if desired. While in the drawings a pulley "9 is shown having a single belt track, a common cone pulley having multiple tracks can be used, and in some instances this will be advantageous, as set forth more clearly hereinafter, to eliminate the necessity of changing pulleys 9 for different size tool pulleys when using one belt 11 size.

Motor 7, drive pulley 9 and belt 11 individually drive and power tools and/or equipment spaced around, over and/ or under a table 13, on which the power tools and/ or equipment are mounted stationarily. The power tools andcompressor 15 shown in the drawings are for explanatory purposes only, and it is to be understood that any power tools and/ or equipment can be employed with the new indexing and mounting means for motor 7 of my invention. The power tools are a sander 17 having pulley 19 to receive operatably belt 11, a sheet metal worker 21 having drive pulley 23 to receive belt 11, and a grinder 25 having drive pulley 27 to receive pulley belt 31. Compressor 15 has drive pulley 16 to receive belt 11, and compressor 15 is mounted on a lower platform 31, which is supported by legs 33 of the table.

Indexing and mounting means 30, shown in detail in Figs. 3, 4 and of the drawings, is a preferred specific structure of my invention. It has a base member 35 which has a lower flange 37 having a plurality of holes 39 therein. Common bolt and nut means (not shown) passes through the holes 39 to mount the base 35 on tabletop 13, such tabletop having corresponding holes therein (not shown). The base is rigidly mounted on tabletop 13. Of course, it can be welded thereto, if desired. The circular base member 35 has a shoulder portion 38, and an upper cylindrical neck portion 41 which projects up wardly when the base member 35 is mounted on tabletop 13.

A cylindrical collar member 43 is mounted on the cylindrical neck portion 41 of base member 35 to rotate thereabout in operation. If desired, several base members 35 can be used mounted on several tables or benches 13, and one collar member 43 and power means 7 mounted thereby can be moved from one to another, as desired, to operate a great number of tools and/ or equipment. A pair of spaced and projecting arm members 45 are rigidly attached to collar 43 in any suitable manner, or they can be integrally formed therewith, and these arm members 45 turn with collar 43. An arm member 47 is attached to and projects from the other side or the portion opposite of collar 43, and as set forth hereinafter, this arm 47 mounts linking assembly and indexing means for the apparatus .of my invention.

A mounting plate or platform 49 is tiltably mounted on arm members 45 and 47, and such mounting results in a platform 49 rotating and turning with collar member 43. The plate or platform 49 is constructed to receive and mount motor 7 so that the motor will tilt with the plate 49 and turn with same. Holes 51 in plate 49' receive nut and bolt means to mount the base of the motor on the platform or plate. Two spaced and downwardly projecting leg members 53 are suitably attached to the underside of plate or platform 49, and these are pivotally mounted on arm members 45 by pins 55.

An upper linking member 57 and a lower linking member 59 are pivotally joined by a pin 61. The upper linking member 57 is fixed in any suitable manner, such as by welding, to a shaft 63 having an operating handle 65 integral therewith, such shaft being pivotally mounted in spaced brackets 67 fixed to the underneath side of plate or platform 49. Thus, when handle 65 is operated to turn shaft 63, link 57 turns to in turn pivot the lower link 59. This lower link 59 is pivoted to arm member 47 by pin 69.

When handle 65- is in the position" of Figs. 1, 2 M114,

4 plate 49 and thus motor 7 is in tilted position (Fig. 5) and belt 11 will be tight ondrive pulley 9 of motor 7 and the pulley on the power tool and/or equipment upon which belt 11 is mounted. Moving handle 64 to the position of Fig. 3 of the drawings, approximately places platform or plate 49 in horizontal position, thus loosening belt 11, and allowing for removing belt 11 from the drive pulley of the power tools and/or equipment. Therefore, by merely tilting platform or plate 49 through the use of handle 65 operator and the linking assembly 57 and 59, the motor 7 is placed in operating position in relation to the tools and/or equipment. Also, I have found it very advantageous to use the mounting means and the pulley belt 11 as a clutch to start and stop the tool being driven, tilting platform 49 with handle 65 engaging and disengaging belt 11 in operation.

The cylindrical and upwardly projecting neck portion 41 of base member 35 has a row of spaced indexing holes 72 therein. Collar member 43 has a hole therein which is alignable with holes 72 in neck portion 41 of base 35. A pin 74 is slidably mounted in the hole in collar 43, such pin 74 being extendable into one of the holes 72 in neck portion 41 of base member 35, as desired, to lock the collar 43 and base 35 against turning of the collar 43 on the base. The other end of pin 74 is slidably mounted in an aperture in an upright portion 75 of the arm member 47. This mounts and supports pin 74. A helical spring 77 acting in compression is mounted around pin 74, and held thereon in operative position by portion 75 of arm 47 and a pin 79 through operating pin 74. This helical spring 77 urges pin 74 into extended position, so that when the hole in collar 43 and one of the indexing holes 72 in neck portion 41 of base 35 coincide, pin 74 will extend to lock the members against relative movement.

Lower link member 59 has an outwardly projecting portion 30. On this portion 84) rests a connecting member 82 which passes through the outer end of pin 74, so that when link 57 pivots member 82 will move outwardly to retract pin 74. I Also, a projecting portion 84 of upper link 57 when in pivoted position, contacts link 82 to finally extend it to fully retract pin 74, to withdraw the outer end of same from one of the holes 72. This occurs when plate or platform 49 is tilted to the position of Fig. 3, the substantially horizontal position, and when in such position collar 43 can be turned on neck portion 41 of base 35 to move the plate or platform 49 and motor 7 to a new position, as desired, to drive a particular tool and/or equipment. Thus, a great number of stationary mounted power tools and/ or equipment can be individually driven by one motor 7 through the use of the new indexing and mounting means of my invention. And, as can easily be seen by those skilled in the art, the power means 7 can be electrically driven or by fuel such as gaso line, without the necessity of starting and stopping to switch power tools or equipment driven, since the drive belt 11 can be disengaged and the motor or engine turned to another position while running.

As will be evident to those skilled in the art, various modifications of this invention can be made, or followed, in the light of this disclosure and discussion, without departing from the spirit or scope of the disclosure or from the scope of the claims.
